Patent CA-2636960-A1 (CA)
Inventor: TAS SINAN
IPC: A61K8/63
Filed: 2003-03-17
Abstract: This invention concerns the use of cyclopamine, a naturally occurring steroidal alkaloid known for over thirty years, for the treatment of psoriasis and achievement of rapid clearance of the psoriatic skin lesions together with the reversion of the histopathological signs of disease to normalcy with no detectable side effects. The cyclopamine-induced clearance of psoriatic lesions from the skin of patients is associated with the causation of cellular differentiation in lesional epidermis and with the rapid disappearance of CD4(+) lymphocytes and other inflammatory cells from lesional skin. Therapeutic compositions comprising of cyclopamine and a corticosteroid and/or the pre-treatment of lesions with a corticosteroid provide significantly further increased therapeutic effectiveness over the use of cyclopamine alone or a corticosteroid alone.
